£9 Jan. The activity count lasted all day - Standen 
ot the wettest watch, but it cleared in the afternoon 
nd was very warm and clear - a real pleasure, 
if prominance were the forays, repeated a gaxnada again, 
fad- Frigate from the N. roost into the central plain 
xjcxnx for twigs. It seemed the bird -would generally 
never over Solanura clones and rip out large twigs of 
the plant - it looked like living strands were broken 
The birds generally came back in flocks ox from 
3 to 8 birds, containing both RBB and Blue-faced Boobies, 
the flocks coming in from the NW and breaking up over K. 
lot. the BFB going to the NAF and tne RFB. landing m t 
ggidsrxlxrwwatx north roost. . ^ 
I One study bird, the cT Laysan on nest 50, was m 
peffect health yesterday. Today ha was una e o^ s n , 
and a hole about 6" be 7" was eaten out of his back. 
I destroyed the bird, and his egg is being Kept under 
lamp in the lab, although it will prooably not haoch. 
After the^ gr ea t^mo vie (Sex and the Single Girl) we 
all had to n go e out for exercise so Dennis and Bob banned 
RFB and Frigates, I worked on Bonins and counted one 
Blue -faced Boobies and Brown Boobies sod on the 1 si . 
T here were few Bonins about, only 19 banded 9 
returns in 3 hours of walking about. 
The numbers of boobies were low - 114 ulue-xaceu 
22 Browns - the latter consists of 10 1mm. 
While banding Bonins I found an injured fairy £ei ' 
an injured Bonin, and a weak Golden Plover, xne Fax.ry 
Tern is being cared for in the lab, the Bonin was destroy 
ed and kept for a skin, and the Plover was banded. 
30 Jan. The shorebird and seal census was carried onxdasjfc 
today. Dennis had the interior. Bob and I toox the 
beaches. An attempt to assay number of Albatross nests , 
hatched revealed some interesting things - hatchin ove 
the island is far from uniform. N. pt. 33 per-cent 
(1 bf 3 nests there) were hatched, 20 ^ 4 per c«no 
hatch in all the rest of the beaches and the runway, 
whereas only 12 per dent hatched in the interior 
(both antenna fields). DOES THE activity of the Black- 
feet on the beaches accelerate egg laying there in the 
Laysans? Anyway, the beaches are ahead of the rest ox 
the island in eggs hatched#
